Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding auxiliary, in particular to an automatic conveying device for slag shell of electrode submerged arc surfacing and a surfacing system. BACKGROUND

[0002] Electrode submerged arc surfacing is a special welding process, mainly used for surfacing a layer of alloy on the metal surface with corrosion resistance, wear resistance or other special properties. This process is particularly suitable for the manufacture of hydrogenation reactor cylinder segments, because the working environment of hydrogenation reactor is usually very harsh, which requires high temperature resistance, high pressure resistance, corrosion resistance and wear resistance. A large amount of slag shell is generated during the electrode submerged arc surfacing of hydrogenation reactor cylinder segments, and the scattered slag shell will affect the welding process, so the welding slag needs to be recycled.

[0003] In the prior art, a slag shell collecting box is arranged at each surfacing station, and the slag shell is collected manually into the slag shell collecting box during welding. After the slag shell collecting box is filled, it needs to be lifted to a designated position by a crown block. Although this can achieve the recycling of slag shell, manual collection of slag shell is time-consuming and laborious, which not only reduces the efficiency of recycling slag shell, but also affects the efficiency of welding. In addition, the slag shell collecting box occupies a large space, affecting the passage of personnel and materials, and the crown block needs to be frequently called, which seriously wastes the resources of the crown block. SUMMARY

The slag guiding groove corresponds to one surfacing station, and the slag receiving end of the slag guiding groove faces the surfacing station for receiving the slag shell generated by the surfacing station. The connecting end of the slag guiding groove is connected to the side of the intermediate section conveyor, and the slag receiving end is higher than the connecting end. The intermediate section conveyor and the final section conveyor are arranged between the surfacing station and a safety passage, and are parallel to the safety passage. All the intermediate section conveyors are connected in sequence from head to tail, and the tail end of the last intermediate section conveyor is connected to the head end of the final section conveyor to convey the slag shell to the final section conveyor. The tail end of the final section conveyor is provided with the slag shell collecting box below to convey the slag shell to the slag shell collecting box. The side of the intermediate section conveyor away from the slag guiding groove is provided with a slag blocking plate, the slag blocking surface of the slag blocking plate faces the slag guiding groove, and the width of the slag blocking surface is greater than the width of the slag guiding groove.

[0006] Optionally, a supporting seat is arranged on the lower surface of the upper slag guide groove, a support is rotatably connected to the supporting seat at a fixed end, and a connecting end of the support is connected to one end of an extendable supporting rod, so that the extendable supporting rod rotates around the supporting seat as a fulcrum, and the other end of the extendable supporting rod is used to abut against the ground.

[0007] Optionally, the intermediate section conveyor comprises a conveyor frame, a conveyor belt, a conveyor belt passing shaft, a conveyor motor and a caster, the conveyor belt passing shaft is arranged inside the conveyor frame and extends along a first direction, the conveyor belt is sleeved on the conveyor belt passing shaft, the conveyor motor is mounted on the conveyor frame and connected to the conveyor belt passing shaft to drive the conveyor belt to move along a second direction, the second direction is perpendicular to the first direction, and the caster is mounted at a bottom end of the conveyor frame to move the intermediate section conveyor.

[0008] Optionally, the conveyor belt comprises a plurality of chain plates, the chain plates are connected end to end in the second direction, and the chain plates are vertically provided with baffle plates at both ends in the first direction, respectively.

[0009] Optionally, the conveyor frame is vertically provided with baffle plates at both sides in the first direction, respectively.

[0010] Optionally, the intermediate section conveyor further comprises a material receiving plate, the material receiving plate is fixed in the conveyor frame and located below the conveyor belt.

[0011] Optionally, the intermediate section conveyor further comprises a tensioning mechanism, the tensioning mechanism is arranged on the conveyor frame and connected to the conveyor belt to adjust the tension of the conveyor belt.

[0012] Optionally, an aluminum alloy profile plate is arranged at a side of the intermediate section conveyor, and the aluminum alloy profile plate is connected to the connecting end of the upper slag guide groove through a hinge.

[0013] Optionally, the automatic conveying device further comprises an electrical control cabinet, the electrical control cabinet is electrically connected to the intermediate section conveyor and the final section conveyor, respectively, to control the opening and closing of the intermediate section conveyor and the final section conveyor.

[0014] In the second aspect, the present application provides a surfacing system comprising the automatic conveying device for slag shell of strip surfacing by submerged arc welding according to the first aspect.

[0015] The automatic conveying device for slag shell of strip surfacing by submerged arc welding and the surfacing system have the following advantages:

[0016] By one-to-one correspondence between the slag guide groove and the surfacing station, and the slag receiving end of the slag guide groove facing the surfacing station, the conveying device can receive the slag shell generated by each surfacing station. Then, through the connection between the connection end of the slag guide groove and the side of the intermediate section conveyor, and the slag receiving end of the slag guide groove being higher than the connection end of the slag guide groove, the slag shell can automatically slide from the slag guide groove to the intermediate section conveyor under the action of gravity. Since the intermediate section conveyor is sequentially connected with other intermediate section conveyors, and the tail end of the last intermediate section conveyor is connected with the head end of the final section conveyor, the slag shell can be transmitted from the intermediate section conveyor to the final section conveyor, and then conveyed to the slag shell collecting box below the tail end of the final section conveyor by the final section conveyor, so that the conveying device forms a continuous conveying line, thereby completing the automatic collection of the slag shell, reducing the dependence on manual labor, reducing labor costs, and greatly improving the collection efficiency.

Moreover, by arranging the slag shell collecting box only at the tail end of the final section conveyor, unified collection and unified calling of the crane for all welding stations can be realized, which not only greatly reduces the number of slag shell collecting boxes, saves costs, but also reduces the frequency of calling the crane, saving crane resources. In addition, by arranging the slag blocking surface of the slag blocking plate facing the slag guide groove, and the width of the slag blocking surface being greater than the width of the slag guide groove, the elastic collision phenomenon caused by excessive gravitational potential energy during the sliding of the slag shell to the intermediate section conveyor can be effectively prevented, the slag shell is prevented from falling when contacting the intermediate section conveyor, and the slag shell collection effect is improved.

[0028] It should be noted that the modification of "one" or "multiple" mentioned in the present application is illustrative and not restrictive, and those skilled in the art should understand that, unless otherwise explicitly indicated in the context, it should be understood as "one or more".

[0029] In view of the problems of the above-mentioned related technologies, such as Figure 1 , Figure 2 and Figure 5As shown in the figure, an automatic conveying device and welding system for slag shell in submerged arc welding provided by an embodiment of the present invention includes at least one slag guide trough 1, at least one intermediate section conveyor 2, at least one final section conveyor 3, and a slag shell collection box 4. The slag guide trough 1 corresponds one-to-one with a welding station 5, and the slag receiving end of the slag guide trough 1 faces the welding station 5 to receive the slag shell generated by the welding station 5. The connecting end of the slag guide trough 1 is connected to the side of the intermediate section conveyor 2, and the slag receiving end is higher than the connecting end. The intermediate section conveyor 2 and the final section conveyor 3 are both located at the welding station 5 and the final section conveyor 4. Between and parallel to the safety passage 6, all the intermediate section conveyors 2 are connected end to end in sequence. The tail end of the last intermediate section conveyor 2 is connected to the head end of the final section conveyor 3 to transport the slag shell to the final section conveyor 3. The tail end of the final section conveyor 3 is provided with a slag shell collection box 4 to transport the slag shell to the slag shell collection box 4. The side of the intermediate section conveyor 2 away from the upper slag guide trough 1 is provided with a slag baffle plate 201. The slag baffle plate 201 faces the upper slag guide trough 1, and the width of the slag baffle plate 201 is greater than the width of the upper slag guide trough 1.

[0030] Specifically, the slag guide trough 1 corresponds one-to-one with each welding station 5, that is, each welding station 5 is equipped with a slag guide trough 1 to collect the slag shell generated at each welding station 5. The slag receiving end of the slag guide trough 1 faces the welding station 5, and the connecting end of the slag guide trough 1 is connected to the side of the intermediate section conveyor 2, with the receiving end higher than the connecting end. Thus, after the slag guide trough 1 receives the slag shell, the slag shell can slide from the receiving end to the connecting end under gravity and enter the intermediate section conveyor 2. The intermediate section conveyor 2 and the final section conveyor 3 are both located between the welding station 5 and the safety passage 6, and are parallel to the safety passage 6. All intermediate section conveyors 2 are connected end-to-end sequentially, with the tail end of the last intermediate section conveyor 2 connected to the head end of the final section conveyor 3. This allows at least one intermediate section conveyor 2 and the final section conveyor 3 to form an automated transport line, such as... Figure 1As shown, seven intermediate conveyors 2 and one final conveyor 3 can be set up to form an automated transport line. This allows the slag shells generated at each welding station 5 to be automatically transported to the slag shell collection box 4 at the end of the line. The tail end of each intermediate conveyor 2 is higher than the head end of the next intermediate conveyor 2, and the tail end of the last intermediate conveyor 2 is higher than the head end of the final conveyor 3. Mechanical connecting pins are used between intermediate conveyors 2 and between intermediate conveyors 2 and the final conveyor 3 to facilitate effective connection of slag shell transport between different conveyors, thus transporting the slag shells to the slag shell collection box 4 below the tail end of the final conveyor 3. On the other side of the intermediate section conveyor 2, that is, the side away from the upper slag guide trough 1, a slag baffle 201 is provided. The bottom of the slag baffle 201 is provided with a sliding groove, the groove opening facing the other side of the intermediate section conveyor 2, and the sliding groove is fastened to the other side of the intermediate section conveyor 2 so that the slag baffle 201 can slide along the conveying direction on the other side of the intermediate section conveyor 2 and can be detached. The slag baffle surface of the slag baffle 201 faces the upper slag guide trough 1 and is at a certain angle to reduce the elastic potential energy converted from gravitational potential energy when the slag shell comes into contact with the intermediate section conveyor 2, thereby avoiding the secondary bounce caused by excessive elastic potential energy that causes the slag shell to fall. The width of the slag baffle surface is greater than the cross-sectional width of the upper slag guide trough 1 so that the slag baffle area is greater than the moving area of ​​the slag shell in the upper slag guide trough 1, so as to maximize the prevention of the slag shell from falling from the intermediate section conveyor 2.

[0031] It should be understood that the structure of the final conveyor 3 can be the same as that of the intermediate conveyor 2. That is, the side of the final conveyor 3 can also be connected to the slag guide chute 1, and the other side of the final conveyor 3 can also be equipped with a slag baffle plate, with the slag baffle surface facing the slag guide chute 1, and the width of the slag baffle surface being greater than the width of the slag guide chute 1. However, the height difference between the beginning and end of the final conveyor 3 is different from the height difference between the beginning and end of the intermediate conveyor 2, and the height difference between the beginning and end of each intermediate conveyor 2 can also be different.

[0032] For example, the lengths of the intermediate section conveyor 2 and the final section conveyor 3 can be set according to actual conditions. For instance, the length of the intermediate section conveyor 2 can be set to 8000mm, and the length of the final section conveyor 3 can be set to 7000mm. This allows at least one slag guide chute 1 to be installed on the side of the intermediate section conveyor 2 and the final section conveyor 3, and the intermediate section conveyor 2 and the final section conveyor 3 are equipped with a number of baffle plates corresponding to the number of slag guide chute 1 to ensure that the slag shell in all the slag guide chute 1s does not fall off. Alternatively, the slag guide chute 1 can be omitted depending on actual conditions, such as... Figure 6As shown, based on the actual situation, there is no welding station 5 at the location of the intermediate section conveyor 2. Therefore, it is not necessary to set up the slag guide chute 1 and the corresponding slag baffle 201. It only transports the slag shell transmitted from other intermediate section conveyors 2 and transfers the slag shell to the next intermediate section conveyor 2. The situation of the terminal section conveyor 3 is similar to that of the intermediate section conveyors 2, and will not be described in detail here.

[0033] In this embodiment, the slag guide trough 1 corresponds one-to-one with the welding station 5, and the slag receiving end of the slag guide trough 1 faces the welding station 5. This allows the conveying device to receive the slag shell generated by each welding station 5. The slag shell is then connected to the side of the intermediate section conveyor 2 through the connecting end of the slag guide trough 1, and the slag receiving end of the slag guide trough 1 is higher than the connecting end of the slag guide trough 1. This allows the slag shell to automatically slide from the slag guide trough 1 into the intermediate section conveyor 2 under the action of gravity. Since the intermediate section conveyor 2 is connected to the other intermediate section conveyors 2 in sequence, and the tail end of the last intermediate section conveyor 2 is connected to the head end of the final section conveyor 3, the slag shell can be transferred from the intermediate section conveyor 2 to the final section conveyor 3. Then, the slag shell is transported to the slag shell collection box 4 below the tail end of the final section conveyor 3, so that the conveying device forms a continuous conveying line, thereby completing the automatic collection of slag shell, reducing the dependence on manual labor, lowering labor costs, and greatly improving collection efficiency. Since both the intermediate conveyor 2 and the final conveyor 3 are located between the welding station 5 and the safety passage 6, and are parallel to the safety passage 6, not only is the effective transportation of slag shells guaranteed, but a safe passage path is also provided, reducing the probability of safety accidents and solving the problem of large space occupation by slag shell collection boxes, which affects the passage of personnel and materials. Moreover, by setting slag shell collection boxes 4 only at the end of the final conveyor 3, unified collection and unified use of overhead cranes for slag shells from all welding stations can be achieved. This not only greatly reduces the number of slag shell collection boxes 4, saving costs, but also reduces the frequency of using overhead cranes, saving overhead crane resources. In addition, by having the slag-blocking surface of the slag-blocking plate 201 facing the upper slag guide trough 1, and the width of the slag-blocking surface being greater than the width of the upper slag guide trough 1, the elastic collision phenomenon caused by excessive gravitational potential energy during the process of slag shells sliding to the intermediate conveyor 2 can be effectively prevented, avoiding the slag shells from falling when in contact with the intermediate conveyor 2, thus improving the slag shell collection effect.

[0034] Optionally, the lower surface of the slag guide channel 1 is provided with a support base 101, a bracket 102, and a telescopic support rod 103. The support base 101 is fixed to the lower surface of the slag guide channel 1. The fixed end of the bracket 102 is rotatably connected to the support base 101. The connecting end of the bracket 102 is connected to one end of the telescopic support rod 103 so that the telescopic support rod 103 rotates around the support base 101 as a fulcrum. The other end of the telescopic support rod 103 is used to abut against the ground.

[0035] Specifically, such as Figure 3 As shown, the lower surface of the slag guide channel 1 is provided with a support base 101, a bracket 102, and a telescopic support rod 103. There are at least two support bases 101, located at both ends of the bracket 102 to fix the bracket 102 to the lower surface of the slag guide channel 1. The support base 101 has a cuboid structure. The bracket 102 includes a first support rod and a second support rod. The first support rod is the fixed end of the bracket 102, and the second support rod is the connecting end of the bracket 102. The second support rod is perpendicular to the middle of the first support rod, i.e., the first and second support rods form a "T" shape. The support 102 has through holes that fit the shape of both ends of the first support rod, allowing the first support rod to pass through and rotate within the through holes, thus achieving a rotatable connection between the support 102 and the support base 101. The second support rod, serving as the connecting end, is then connected to one end of the telescopic support rod 103, allowing the telescopic support rod 103 to rotate around the support base 101, thereby adjusting the support angle of the telescopic support rod 103. Furthermore, the telescopic nature of the telescopic support rod 103 allows for adjustment of its support height, which in turn adjusts the height of the slag receiving end of the slag guide trough 1. The welding station 5 includes petrochemical product cylinder sections, cylinder section rollers, and a heavy-duty submerged arc welding manipulator. By adjusting the slag receiving end of the slag guide trough 1 to a suitable height, it not only does not affect the welding of the petrochemical product cylinder sections by the heavy-duty submerged arc welding manipulator, but also facilitates the introduction of slag shells into the slag guide trough 1.

[0036] For example, the bracket 102 can be fixed to the lower surface of the slag guide trough 1 near the slag receiving end, for example, 500mm from the slag receiving end port, to increase the supporting torque, improve the supporting effect, and facilitate changing the height of the slag receiving end. The telescopic support rod 103 can also be set with a telescopic range of 600mm-1600mm to adapt to different situations and increase the adaptability and flexibility of the device.

[0037] Optionally, the intermediate section conveyor 2 includes a conveyor frame 202, a conveyor belt 203, a conveyor belt through shaft 204, a conveyor motor 205, and casters 206. The conveyor belt through shaft 204 is disposed inside the conveyor frame 202 and extends along a first direction. The conveyor belt 203 is sleeved on the conveyor belt through shaft 204. The conveyor motor 205 is mounted on the conveyor frame 202 and connected to the conveyor belt through shaft 204 for driving the conveyor belt 203 to move along a second direction, which is perpendicular to the first direction. The casters 206 are mounted at the bottom of the conveyor frame 202 for moving the intermediate section conveyor 2.

[0038] Specifically, such as Figure 4As shown, the intermediate section conveyor 2 includes a conveyor frame 202, a conveyor belt 203, a conveyor belt shaft 204, a conveyor motor 205, and casters 206. The conveyor frame 202 can be made of aluminum alloy profile. The conveyor belt shaft 204 is horizontally arranged inside the conveyor frame 202, and the conveyor belt 203 is sleeved on the conveyor belt shaft 204. The conveyor motor 205 is mounted on the conveyor frame 202 and connected to the conveyor belt shaft 204 to drive the conveyor belt 203. For example, the conveyor motor 205 can be a three-phase asynchronous motor and connected to the conveyor belt shaft 204 through a worm gear reducer to achieve power transmission and speed adjustment. The casters 206 are installed at the bottom of the conveyor frame 202, and there are multiple casters 206. The casters 206 can be movable casters to move the intermediate section conveyor 2.

[0039] Optionally, the conveyor belt 203 includes a plurality of chain plates 2031 connected end to end in the second direction, and the chain plates 2031 are respectively provided with baffles 2032 at both ends in the first direction.

[0040] Specifically, such as Figure 7 As shown, the conveyor belt 203 includes multiple chain plates 2031. Each chain plate 2031 has connecting pin holes spaced apart on both sides in the second direction to connect with other chain plates 2031 and splice them into a conveyor belt 203. Each end of the chain plate 2031 in the first direction is provided with a baffle 2032. The height of the baffle 2032 can be set according to the actual situation to prevent small slag shells from falling from the conveyor belt into the conveyor, thus preventing the slag shells from jamming the operating conveyor. The surface of the baffle 2032 is streamlined, which can block the slag shells at multiple angles and increase the blocking range.

[0041] Optionally, the conveyor frame 202 is provided with guard plates 207 perpendicularly on both sides in the first direction.

[0042] Specifically, such as Figure 4 and Figure 6 As shown, the conveyor frame 202 is provided with guard plates 207 on both sides of the first direction. The guard plates 207 are higher than the conveyor belt 203 to prevent the slag shell from falling off the middle section conveyor 2.

[0043] Optionally, the intermediate section conveyor 2 further includes a receiving plate 208, which is fixed in the conveyor frame 202 and located below the conveyor belt 203.

[0044] Specifically, such as Figure 4 and Figure 6As shown, since tiny slag shells or powdered flux can pass through the gaps in the conveyor belt and fall into the intermediate section conveyor 2, the intermediate section conveyor 2 is also equipped with a receiving plate 208. The receiving plate 208 is fixed in the conveyor frame 202 and located below the conveyor belt 203 to collect tiny slag shells or powdered flux and to uniformly process the slag shells or powdered flux on the receiving plate 208.

[0045] Optionally, the intermediate section conveyor 2 further includes a tensioning mechanism 209, which is disposed on the conveyor frame 202 and connected to the conveyor belt 203 for adjusting the tension of the conveyor belt 203.

[0046] Specifically, such as Figure 4 and Figure 6 As shown, the intermediate section conveyor 2 also includes a tensioning mechanism 209, which is mounted on the conveyor frame 202 and connected to the conveyor belt 203. The tensioning mechanism 209 is used to adjust the tension of the conveyor belt 203 to ensure that the conveyor belt 203 maintains appropriate tension during operation and to avoid equipment failure caused by the conveyor belt 203 being too loose or too tight.

[0047] Optionally, the side of the intermediate section conveyor 2 is provided with an aluminum alloy profile plate 210, which is connected to the connecting end of the slag guide trough 1 via a hinge 211.

[0048] Specifically, such as Figures 2 to 4 As shown, the side of the intermediate section conveyor 2 is provided with an aluminum alloy profile plate 210. The aluminum alloy profile plate 210 is connected to the connecting end of the slag guide trough 1 through a hinge 211, so that the slag guide trough 1 can rotate based on the hinge 211, thereby changing the direction of the slag receiving end.

[0049] It should be understood that the structure of the final section conveyor 3 may be the same as that of the intermediate section conveyor 2. That is, the final section conveyor 3 may include at least one of the following structures: slag baffle, conveyor frame, conveyor belt, chain plate, baffle, conveyor belt through shaft, conveyor motor, casters, guard plate, receiving plate, tensioning mechanism, aluminum alloy profile plate and hinge.

[0050] Optionally, the automatic conveying device further includes an electrical control cabinet, which is electrically connected to the intermediate section conveyor 2 and the final section conveyor 3 respectively, and is used to control the opening and closing of the intermediate section conveyor 2 and the final section conveyor 3.

[0051] Specifically, the automatic conveying device also includes an electrical control cabinet, which is electrically connected to the intermediate section conveyor 2 and the final section conveyor 3 respectively, and is used to control the opening and closing of the intermediate section conveyor 2 and the final section conveyor 3. The electrical control cabinet includes at least one frequency converter, a processor and a human-machine interface touch screen. The frequency converter, the processor and the human-machine interface touch screen can be connected by a frequency conversion control circuit, and are electrically connected to the conveying motors of the intermediate section conveyor 2 and the final section conveyor 3 through the control terminals in the frequency conversion control circuit, so as to realize the frequency conversion speed regulation of the intermediate section conveyor 2 and the final section conveyor 3.

[0052] The processor stores the PLC control program and the human-machine interface (HMI) configuration program. The PLC control program controls the rotation direction of the conveyor motors of the intermediate section conveyor 2 and the final section conveyor 3, thereby controlling the rotation of the conveyor drums to achieve the purpose of transporting slag shells. The PLC control program is also responsible for all data calculation, storage, data transmission, and related data processing, and sends commands to other devices and receives signals from other devices. The HMI configuration program mainly realizes the information interaction between the operator and the equipment, meeting the functions of speed, comfort, and practicality. It is presented through the HMI touch screen. The HMI configuration program can be used to process real-time data from the controller in the electrical control cabinet and display parameters such as current operating speed and alarm display in real time through the HMI touch screen. In addition, the electrical control cabinet is equipped with start, stop, forward, reverse, emergency stop, and power indicator buttons. Emergency stop buttons are also provided on the sides of the intermediate section conveyor 2 and the final section conveyor 3. The conveyor heads and tails are equipped with aviation male and female plugs, and the automatic conveying device is equipped with circuit breakers of appropriate load specifications.

[0053] For example, the electrical control cabinet can be located on the side of the welding station 5. A centralized control mode can be set via a PLC control program to achieve centralized control of the intermediate section conveyor 2 and the final section conveyor 3. The PLC control program can also be used to set manual control and automatic operation of the intermediate section conveyor 2 and the final section conveyor 3. Under manual control, the start and stop of the strip-electrode submerged arc welding can be controlled individually, and the speed of each intermediate section conveyor 2 and the final section conveyor 3 can be adjusted independently. Under automatic control, a continuous operation strategy or an intermittent operation strategy can be adopted, and the operating interval time can also be set to meet different usage requirements. The setting and monitoring of parameters in the PLC control program and the human-machine interface configuration program can be completed based on the human-machine interface touch screen. For example, the settings for power parameters (ON / OFF), frequency parameters (50Hz), status parameters (start / stop), fault indication parameters (normal / fault), intermittent motion parameters (start / stop), stop time parameters (0-5min), and start time parameters (0-5min) can be configured.

[0054] An embodiment of the present invention provides a welding system, including an automatic conveying device for slag shell of submerged arc welding as described above.

[0055] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
